This is a simple structure, which contains ``name``, ``type``, ``len``, ``dec`` and ``cls`` fields. Objects also implement get/setitem magic functions, so fields could be accessed via sequence interface, where 'name' has index 0, 'type' index 1, 'len' index 2, 'dec' index 3 and 'cls' could be located at index 4. )nametypelendecclsNr)CNLDTcCsL|j|\}}|dkr*|dkr&td|}||_||_||_||_||_dS)NzField length must be defined) FLD_TYPES ValueErrorrr r r r )selfrr r r _cls_lenr@/tmp/pip-unpacked-wheel-_3ph8cfy/tablib/packages/dbfpy/dbfnew.py__init__?sz_FieldDefinition.__init__cCs||j|j|jS)z:Return `DbfFieldDef` instance from the current definition.)r rr r rrrr getDbfFieldKsz_FieldDefinition.getDbfFieldcCs|}||dS)zCreate a `DbfFieldDef` instance and append it to the dbf header.

Arguments: name: field name (str object). field name must not contain ASCII NULs and it's length shouldn't exceed 10 characters. typ: type of the field. this must be a single character from the "CNLMDT" set meaning character, numeric, logical, memo, date and date/time respectively. len: length of the field. this argument is used only for the character and numeric fields. all other fields have fixed length. FIXME: use None as a default for this argument? dec: decimal precision. used only for the numric fields.
